Ditto what was said above. The only way to have a "natural" swimming pool is to have the same size bio filter next to the swimming pond, which is filled with plants that will utilize nutrients that are in the water, and use a pump to circulate water from the swimming pond through the bio filter. Those nutrients are feeding the algae.

Without any fish in there (even fathead minnows) you will be creating a perfect habitat for mosquitoes to reproduce.

This site has more detailed information for you.
